Translation of gratis in German

It was after midnight when we finally could go to bed and rest a little. It was good that the search for a better room turned out to be funny and amuzing so that we did not feel sorry about it.
We decided to walk back and explore the city on foot. It was hard to cross the streets as there was an endless flow of motorcycles and bikes. One needed to just enter the street and cross it.
Fortunately and against all odds there were seats available so that we changed our booking to the same day. Our destination was El Calafate in the South of Patagonia in order to see the glaciers.
